Jessie, who sits on the show's panel alongside Will.i.am, Sir Tom Jones and Danny O'Donoghue, described her fellow coaches as "wonderful".
In an interview with More magazine, the 23-year-old singer refused to pick a favourite, insisting she couldn't chose between the trio of stars.
"Am I allowed to say all of them?" Jessie told the publication. "They're all wonderful."
The 'Domino' hitmaker went on to explain: "I'm like a sponge around Tom, just soaking up all his timeless energy as an artist.
"Will.i.am and I just really get each other and we're really silly together, but he's serious when he needs to be and I'm the same.
"Danny's just the sweetest guy. He's definitely going to be the heart-throb of the show, I think, just look at his eyelashes!"
The Voice UK continues on Saturday night at 7PM
